Description

Technical Field

[0001] This utility model belongs to the field of motorcycle technology, and more specifically, it is a wheel hub bolt anti-reverse structure. Background Technology

[0002] Conventional motorcycle wheel hubs are secured by several bolts passing through several mounting holes and tightening into threaded holes on the axle. Current technology lacks a structural design to prevent bolt loosening. If bolts loosen over long-term use, it increases the likelihood of the hub detaching from the axle, posing a safety hazard to the vehicle. While multiple bolts can reduce the possibility of hub-axle detachment, the loosening of any bolt will alter the locking and stress state between the hub and axle, accelerating component wear and deformation, and also creating safety risks. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a wheel hub bolt anti-retraction structure, which effectively prevents the wheel hub bolt from loosening and falling off due to external factors, thereby improving safety.

[0004] This utility model provides the following technical solution: a wheel hub bolt anti-reverse structure, including a wheel hub body, a plurality of first through holes for mounting first bolts are provided on the wheel hub body along the circumferential direction, an anti-reverse plate is detachably installed on the outer side of the wheel hub body, a plurality of second through holes for mounting second bolts are provided on the anti-reverse plate along the circumferential direction, and mounting holes are provided on the wheel hub body corresponding to the second through holes. When the anti-reverse plate is installed on the outer side of the wheel hub body, it blocks the first bolts and the first through holes.

[0005] As an improvement, the diameter of the anti-reverse plate is larger than that of the first through hole, thereby completely covering the first through hole.

[0006] As an improvement, a viewing window is provided on the anti-reverse plate at the position corresponding to the first through hole, and the size of the viewing window is smaller than the size of the first bolt.

[0007] As an improvement, the anti-reverse plate is a flat, circular piece, with the center of the anti-reverse plate covering the hole in the center of the wheel hub body and the inner axle.

[0008] As an improvement, 4-6 first through holes are evenly distributed on the hub body, the number of mounting holes is the same as the number of first through holes, and the mounting holes are spaced apart from the first through holes and are equally spaced.

[0009] The beneficial effects of this utility model are as follows: By setting the anti-reverse plate, it is stably installed on the wheel hub body to block the first bolt on the periphery, effectively preventing the wheel hub bolt from loosening and falling off due to external factors. This can greatly improve the safety of vehicle use, protect the personal safety of the driver, and is conducive to the long-term use of the vehicle and tires. Attached Figure Description

[0011] Figure 2 This is an exploded three-dimensional structural diagram of the present invention. Detailed Implementation

[0012] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0013] like Figure 1 , 2 The image shows a specific embodiment of the wheel hub bolt anti-reverse structure of this utility model. This embodiment includes a wheel hub body 1, with several first through holes 11 arranged along the circumferential direction for mounting first bolts 2. An anti-reverse plate 3 is detachably mounted on the outer side of the wheel hub body 1, with several second through holes 31 arranged along the circumferential direction for mounting second bolts 4. Assembly holes 12 are provided on the wheel hub body 1 corresponding to the second through holes 31. When the anti-reverse plate 3 is installed on the outer side of the wheel hub body 1, it blocks the first bolts 2 and the first through holes 11.

[0014] In use, the wheel hub body 1 and axle A utilize the existing structure, eliminating the need for re-molding and reducing the cost of redesigning the equipment. As an improvement, mounting holes 12 are machined into the existing wheel hub body 1. The anti-reverse plate 3 is manufactured according to the circumferential dimensions of the first through hole 11. After aligning the wheel hub body 1 and axle A, the first bolt 2 is inserted through the first through hole 11 and installed onto the axle A. Then, the anti-reverse plate 3 is aligned with the wheel hub body 1 and installed onto the wheel hub body 1 (at mounting hole 12) through the second through hole 31 using a second bolt 4. The anti-reverse plate 3 blocks the first bolt 2 and the first through hole 11 from the outside, effectively preventing the wheel hub bolts from loosening and falling off due to external factors, greatly improving the safety of the vehicle and tires. In practice, the anti-reverse plate 3 only blocks the positions of the first bolt 2 and the first through hole 11, without contacting or pressing them, and therefore does not affect or interfere with the locking state of the first bolt 2. The design of the anti-rollover plate 3 does not increase the cost of equipment components, but greatly improves the safety of wheel use, which is conducive to its widespread use.

[0015] As an improved specific implementation, the diameter of the anti-reverse plate 3 is larger than the location of the first through hole 11, thereby completely covering the first through hole 11.

[0016] like Figure 1As shown, the size design of the anti-retraction plate 3 effectively covers the first through hole 11 and the structure therein, and protects the inner structure. Under the premise of ensuring that the first bolt 2 will not come out or fall off, the structural protection of the first through hole 11 and the first bolt 2 is further improved.

[0017] As an improved specific implementation, a viewing window 32 for observation is provided on the anti-reverse plate 3 at the position corresponding to the first through hole 11, and the size of the viewing window 32 is smaller than the size of the first bolt 2.

[0018] like Figure 1 , 2 As shown, in a specific implementation, the viewing window 32 can be set as a circular hole corresponding to the first through hole 11 and the first bolt 2, so that the first bolt 2 can be directly observed and inspected for any abnormalities, such as loosening or damage. The size of the viewing window 32 is smaller than the size of the first bolt 2, so as to effectively prevent the first bolt 2 from coming out.

[0019] As an improved specific implementation, the anti-reverse plate 3 is a sheet-like circular shape, and the middle part of the anti-reverse plate 3 covers the hole in the middle of the wheel hub body 1 and the inner axle.

[0020] like Figure 1 , 2 As shown, the anti-reverse plate 3 is a sheet-like circular shape that matches the size of the wheel hub body 1. After assembly, it forms a complete integrated structure with the wheel hub body 1, which helps to ensure the structural aesthetics of the outer side of the wheel. Furthermore, the circular structure of the anti-reverse plate 3 provides structural protection for the holes in the middle of the wheel hub body 1 and the axle A on the inner side, effectively protecting the internal structure, preventing debris from falling in, and improving the safety of wheel use.

[0021] As an improved specific implementation, 4-6 first through holes 11 are evenly arranged on the hub body 1, and the number of mounting holes 12 is the same as the number of first through holes 11. The mounting holes 12 and the first through holes 11 are spaced apart and equally spaced.

[0022] like Figure 1 , 2 As shown, the first through hole 11 and the mounting hole 12 are evenly arranged at equal angles, so that the hub body 1, axle A, and anti-reverse plate 3 are structurally stable after installation, and the multi-position locking ensures the integrity and stability of the installation.

[0023] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
